l citizen of the United States, and a residentof Yolo? in the Acounty 'of Yold and `Statedof 45;,( aliform'a, have invented fa new. and Im-l provedoldering-Iron, of Which the following is a full, clear, and exact description. l

The invention relates to afsoldering iron of thatl class in .which a liquid fuelreservoir is 0. combined with ltheliren and certain devices for gasifyingthe saidfueL-so that the gasl may beburnedwith a: Bunsen flame to heat the iron-..1 r n Theinven ion resides in certain'secial features of c onstruction'and combination of parts, vand v,all Will'be fully` Set forth hereinp after and particularly pointed out in the claims. f

1 Oindicatesl the gasolene or other volatile liquid fuel reservoir, which is provided with a perforate jacket 11. of' suitable material, and has heads12and lescrewed on its respective ends.` Fastened 'to the head 12 is a screw 'closure .15 which carries within the reservoir .a cylinder 16.- -In this cylinder.

By means -of this device the finger 'piece 19 maybe released at will from the stopsQO,

and the piston 17 operated to force air in tol the reservoir 10,"thus causing the-"volatile liquid fuel therein to 'be forced from the .Specificationof'LettersiPatent. ."Patentedbee,`- application and Mayenlsos.' seria1N.e`19 ,52 i.f f

Having; thus described the preferred form of my invention, What- I actually claim aand desire to seeureby'L'etters Patent is:

1 A soldering'iron,'lcom'prising a reservoir for liquid fuel, an air' pump inthe reservoir, a

erforated hood within the 'reservoir at the innerend thereof, an outlet tube securedto the inner end of the reservoir and. extending into the hood, a generator tubepsec'ured to` lthe outlet tube, `a spring-pressed valve for -the generator tube, means for operatingthe valve, a cup secured to the generating tube and having vafBun'sen tube projecting \.ee'n-.

trally therefrom, aperforated shell secured to the cup and projecting beyond the same, andl a head secured tothe she l.

. 2. A soldering 1ron`, comprising a reservoir 55` fori iiq'nid fuel,- means for f orcing'liquid fuel therefrom, .an'outlet extending -into the reservoir and .having means therein for obstructing the ow of the liq/uid fuel, agenerator tube secured to' the outlet 'tube and proj ecting beyond the reservoir, a valve for the, "generator tube, means -for i operating the i valve, a Bunsen tube projecting beyond the of the Bunsen tube, a perforated shell secured to the' cup and'inclosing the Bunsen tube, and ahead secured to the shell,` and having rearwardly inclined dischargefpassages.` l '1 8'. Ina soldering iron, areservoir for liquid jfuel, means for forcing tle fiel from the resl the valye stein, ai burner carried by the gen- :erator tube, and a head: adjacent to the burner. f' l yIn testimon'y'wvhereof I have signed my -nanie to this specification in the nresence of tWo subscribing Witnesses.y
